Stockpiling

Nope, the exact opposite!
Around 40(!) puzzles have been written but I still feel the big picture is not ready. Also when one idea reaches the editing process, a bigger idea just craves to be made. I promise exciting things are to come but I don’t want to give any dates yet.

Offline things; last year, I won the Sudoku Northern Championship ahead of a field of almost 100 solvers (though mostly novice). The event is happening again next weekend and a tough field is travelling from Bangkok for my scalp. Sinchai is coming as well and he’s probably going to win it – the guy finished 10th in the Sudoku GP, uh, here take my title.

In the meantime, I’ll get through some more Flashbacks, which are currently about 5 years behind.Until then!

What do crosswords in your newspaper, that numbered 9x9 grid that’s suddenly everywhere, the spot the differences on a cereal box, a chess position from some tournament match, the squiggles you see in common IQ tests and a high school mathematics exam have in common?

Answer: They can all be classified as a “puzzle”.
As a lifelong puzzler, I always find the word “puzzle” to be a bit broad. Everyone has their own definition of a puzzle. I imagine a certain place where all puzzle types gather and made known to everyone. That place would be Somewhere Over the Rainbow.
